Abstract: An apparatus for measuring the effectiveness of stray light suppression light shields and baffle arrangements used in optical space experiments. The light shield and baffle arrangement and a telescope model are contained in a vacuum chamber. A source of short, high-powered light energy illuminates portions of the light shield and baffle arrangement and reflects a portion of same to a photomultiplier tube by virtue of multipath scattering. The resulting signal is transferred to time-channel electronics timed by the firing of the high energy light source allowing time discrimination of the signal thereby enabling the light scattered and suppressed by the model to be distinguished from the walls and holders around the apparatus.

Abstract: An improvement in a dough ball pressing apparatus in which the continuous conveyor belt is provided with metal strips at predetermined spaced locations along each edge of the conveyor belt and a pair of proximity switches are positioned on the apparatus adjacent the edges of the conveyor belt for detecting the metal strips. The proximity switches cause the belt driving mechanism to stop upon detecting a metal strip for precisely locating the belt and controlling the distance of travel in each cycle. The conveyor belt is provided as a flat length with ends that are realeasably connected by a pin for allowing easy installation of the belt without disassembling the belt drive mechanism.

Abstract: Water is sprayed onto the surface of a bank of conduits or tubes extending through a heat exchange compartment, which conduits carry the hot exhaust gases from a diesel engine at a temperature of approximately 950. degree. -1100. degree. F. The water is sprayed at such a rate that a substantial portion of the water is reformed into a mixture of hydrogen and oxygen gas and steam. The hydrogen is then mixed with air to form hydrogen enriched air which is introduced into the combustion chamber. When the hydrogen enriched air is compressed, the diesel fuel is introduced with a resulting improvement in fuel efficiency and maximized combustion of the fuel. The water is delivered to the hydrogen generator responsive to the activation of the accelerator pedal at a controlled rate in which the percentage of water to diesel fuel is substantially in the range of 5% to 10%. Air from the engine turbosupercharger is delivered to the hydrogen generator to pick up and carry the hydrogen gas back to the air intake of the engine. Both the diesel fuel and water may be preheated to maximize results.

Abstract: A notch filter for the selective attenuation of a narrow band of frequencies out of a larger band wherein a helical resonator is connected to an input circuit and an output circuit through discrete and equal capacitors, and a resistor is connected between the input and the output circuits.

Abstract: In some implementations, a cooler reduces the temperature of pressed dough balls after the pressed dough balls have been baked in an oven. The cooler may include multiple cooling conveyors arranged in a vertical stack with adjacent conveyors transferring the pressed dough balls in opposite directions. The cooler may include a safety release turnaround between each of the adjacent cooling conveyors to move the pressed dough balls between the adjacent conveyors in the cooler.
